crypto: inside-secure/eip93 - make it selectable for ECONET

Econet SoCs feature an integrated EIP93 in revision 3.0p1. It is identical
to the one used by the Airoha AN7581 and the MediaTek MT7621. Ahmed reports
that the EN7528 passes testmgr's self-tests. This driver should also work
on other little endian Econet SoCs.
